Zoology and wildlife conservation

The study presents a 210,000-year (210-kyr) record of wet periods that is obtained from speleothems and travertine deposits that are accurately dated using the U/Th method of the tropical northeastern Brazil. It concluded that the wet periods probably affected rainforest distribution, as plant fossils show that forest expansion occurred during these intermittent wet intervals, and opened a forest corridor between the Amazonian and Atlantic rainforests.

Early human occupation of the Red Sea coast of Eritrea during the last interglacial

Article Abstract:

Stone Age artefacts discovered on the Red Sea coast of modern-day Eritrea lend support to the 'out of Africa' hypothesis of human origins. The finds suggest human adaptation to a coastal marine environment and a widespread adaptive strategy underpinning expansion of human behaviour.
